Disney•Pixar have issued a press release about their upcoming projects after "Brave" this year and "Monsters University" next year. In the process came a few new tidbits of information.
First up the previously untitled Bob Peterson-helmed dinosaur film now has a name, "The Good Dinosaur", and a release date of May 30th 2014. The premise is based on the idea that the cataclysmic asteroid that wiped out the giant dinosaurs didn't arrive - as a result they never became extinct.
Then there's first word on a new project from "Toy Story 3" director Lee Unkrich which is being described as a "wholly original Pixar Animation Studios film that delves into the vibrant holiday of Día de los Muertos". It currently has a "Dia de los Muertos" working title and rough 2015 date, however both could well change.
Finally the untitled Pete Docter-direct film has been pushed back a year to June 19th 2015. The only detail of the story is the same log line we've been hearing for some time - that the action will be set in the world inside the human mind.

While Pixar's upcoming Dia De Los Muertos is still years out from release, we've already learned about a few key components of the film. For one, the feature will be helmed by Toy Story 3 director Lee Unkirch. It will also explore the Mexican culture's uplifting view of death. (The film's title, translated in English, means "Day of the Dead.")
Now, Disney and Pixar CCO John Lasseter has revealed a few more tidbits on the project, describing it as a "really a fantastic story of family." While no other details have been divulged, /Film speculates that the movie could center on a human protagonist who suffers from a death in the family and explores the ritualistic heritage of the Mexican holiday as a call to action -- an interesting theory, although this is purely based on an educated guess.
In the meantime, the studio still has several other projects lined up to come out before this one, including Monsters University, The Good Dinosaur and Pixar's untitled film set in the human mind

After raising the ire of critics online, The Walt Disney Company quickly backed away today from its move to quietly trademark “Dia de los Muertos” for an upcoming Pixar animated feature. Criticism exploded on social media in recent days as word spread of Disney’s efforts to trademark the name associated with the November holiday. Although the studio still is moving forward on its Pixar project inspired by Mexican Day of the Dead celebrations, it has withdrawn its application to trademark “Dia de los Muertos” for various merchandising applications. “As we have previously announced, Disney-Pixar is developing an animated feature inspired by the Mexican holiday Dia de los Muertos”, the studio said in a statement. “Disney’s trademark filing was intended to protect any potential title for our film and related activities. It has since been determined that the title of the film will change, and therefore we are withdrawing our trademark filing”. Pixar’s Dia de los Muertos film was announced last April and will be directed by Oscar-winning Toy Story 3 helmer Lee Unkrich with Darla K. Anderson producing.

Coco follows the secret musical ambitions of Miguel, who resides in a lively, loud Mexican village but comes from a family of shoemakers that may be the town’s only music-hating household. For generations, the Riveras have banned music because they believe they’ve been cursed by it; as their family history goes, Miguel’s great-great-grandfather abandoned his wife decades earlier to follow his own dreams of performing, leaving Imelda (Miguel’s great-great-grandmother) to take control as the matriarch of the now-thriving Rivera line and declare music dead to the family forever.

But Miguel harbors a secret desire to seize his musical moment, inspired by his favorite singer of all time, the late Ernesto de la Cruz. It’s only after Miguel discovers an amazing link between himself and De la Cruz that he takes action to emulate the famous singer and, in doing so, accidentally enters the Land of the Dead.

In the beautiful underworld, it’s not long until Miguel encounters the souls of his own family — generations’ worth of long-dead but no less vivacious Rivera ancestors, including great-grandmother Imelda. Still, given the opportunity to roam around the Land of the Dead, Miguel decides to track down De la Cruz himself. He teams up with another friendly (and skeletal) spirit — a trickster named Hector, voiced by Bernal — to find De la Cruz, earn his family’s blessing to perform, and return to the Land of the Living before time runs out.

They also confirmed that the movie will have an all-Latino voice cast.

I know some are gonna compare it to the Book of Life, but this one seems a lot more interesting.
